You don't want to use the gear box with the kdrill. It is made to run around 550 rpm. I get more holes out of a battery now that I put the clam plate on. Mine is a direct drive.
I have straight talk now and I doubt I'll ever go back to Verizon. The only spots I don't have good service is spots I didn't have good service with Verizon. I only have the 5gb plan for 45$ I rarely use it all but I do have internet at home.
